Teladi is the name of one of the races in the PC game X2 The Threat. This particular race focuses on trading and has built quite an empire in the X2 universe.
The X2 game is a space simulation that allows the player to build an empire of trading stations and battle fleets. The game features superb graphics and sound and is a far more cerebral game than previous space simulation efforts on the PC platform. It is a spiritual successor to the original Elite space simulation.
